Chemical Structure

3-Chloro-7-phenyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one CAS 83809-91-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-7-phenyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 3-Chloro-7-phenyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one (CAS 83809-91-0), a certified reference material (molecular formula C10H6ClN5O, MW 247.64 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
